I think you will find more light output from the conventionals. I work for a theatrical supplier and we are finding less output with the LED's. We feel that in a few years LED's will be a lot more common in theatre, but right now they are not getting the output needed for the stage. It also depends on who makes the fixtrue and what the wattage is. I would call your local supplier and talk with their sales staff. We bring demo fixture in for people all thim. Maybe someone local to you can do the same and you can test both types in your space. Good luck!
